Title: Spark gap protection device

Abstract: A spark gap protection device is provided. The device comprises a plurality of spark gaps and a plurality of windings. Each spark gap is connected to at least one winding which is inductively coupled to an associated winding connected to another spark gap so that, in use, a surge current flowing across a spark gap and through a winding connected to the spark gap induces a voltage in the associated inductively coupled winding connected to another spark gap. This forces the other spark gap to trigger, thereby distributing the surge current between the spark gaps.
